I was able to grab a copy of Harry Eisenberg's early-90s book about Jeopardy, and in there, he mentions that the show struck a deal with home game makers that essentially said the show's writers would cook up extra material for use in the board/video games, in exchange for x amount of money.
Was this the case with the other game show video/PC game releases from the 80s/early 90s? GameTek was the biggest game show licensee of them all in those days, I think—I'm wondering if they grabbed content directly from the show's writers, or if they had people in-house who whipped all that stuff up.
